• pulley means operatively disposed atop said mast;
• an elongated flexible connector means having an intermediate portion operatively disposed over said pulley means, having one end portion operatively secured to a selected position on the opposite end portion of said boom means, and having an opposite end portion;
• trolley means including a vertical guide for enabling said trolley means to reciprocate vertically up and down, said trolley means including means for operatively securing said opposite end portion of said connector means thereto for raising and lowering said boom as said trolley means is raised and lowered;
• sprocket and pulley means for selectively raising and lowering said trolley means;
• motor means for driving said sprocket and pulley means;
• and
• motor control means operably disposed within easy reach of said prone patient for enabling said prone patient to selectively operate said motor means.

A portable motorized lift apparatus for assisting a prone patient on a bed who cannot sit up under his own power due to the fact that the patient is crippled, injured, or otherwise incapacitated to achieve a sitting position on the bed without the assistance of another human being and such that the weight of the patient's upper body and head is substantially positioned over his hips thereby enabling the patient to do therapeutic exercises or the like from the sitting position or to tense his muscles or joints so as to be able to control his body and slide off of the bed and into a wheelchair of the like for various purposes, said lift apparatus comprising:

• gripping means adapted to be grasped by at least one of the patients hands, wrists, forearm, inner elbow, upper arm, and arm pit;
• derrick means including a boom means for suspending said gripping means in a desired position above the prone patient so as to enable the patient to grasp the gripping means as required;
• said derrick means further including an upright beam and means for supporting same in a vertically upright position;
• pulley means operatively mounted atop said upright beam;
• trolley means including a trolley, a vertical upright support guide post, and an idler pulley operatively coupled to an upper portion of said upright beam;
• cable means operatively disposed over said pulley means and having one end operatively coupled to the front end portion of said boom and the opposite end portion operatively coupled to said trolley for enabling said boom to be raised and lowered as said trolley is lowered and raised;
• motor drive means including a motor, motor control, and a sprocket drive, and drive means operatively coupled about said sprocket drive and over said idler pulley such that one end is operatively coupled to the top of said trolley and the opposite end is coupled to the bottom of said trolley for raising and lowering said trolley by operating said motor in forward or reverse directions;
• and
• manually operable means for enabling the prone patient to selectively control the operation of said motor and hence the raising and lowering of said gripping means, as desired and without the assistance of a second party.
